WARP-HEDDLING MACHINE.

Application filed July 20,1925, Serial No. 44,874, and in. Switzerland July 21, 1924.

the other immediately from the row oi? heddles essentially limits the working speed of the machine; i'urthern'iore extraordinary ditficulties present themselves with heddles which easily become entangled, such as steel heddles.

In order to ensure a safe and reliable operation of the machine at an increased working speed and when handling any type of heddles, so that heddle alter heddle receives its respective warp thread, according to the present invention every single device for separating the heddles is provided with a feeder adapted to separate the heddles into groups from the respective row of heddles and to transport a separated group of heddies to receiving means. A gripping device supplies one heddle after the other from said means to a second place for successively receiving the heddles of the separating device. The heddle at such second place is presented to the holding members moved towards the heddle for securing the latter in position during the passage oi? the threading needle. The threaded heddle is pushed aside by supporting means, in which move ment the threading needle which is preterably rigidly connected to said supporting means partakes, whereupon the threading needle is then withdrawn and returns into its initial position together with the sup porting means.

A constructional example oi the subject matter of the present invention is illustrated on the accompanying drawings, in which:

Figs. 26, 27 and 28 show the parts of the device for separating the heddles in different working positions.

Fig. 29 shows a diagram of the electric connection to the safety device controlled by the threading device.

To the upper support 2 of the machine frame 1 the harnesses 3 (Figs. 1, 2 and 5) are attached by. threading the eyelets at the ends of the heddles to bars provided to that end on the support 2; in Fig. 1 six harnesses are shown. On the lower rails of the frame 1 a carriage 4: is guided in the longitudinal direction of the harnesses, onthis carriage the pattern mechanism 5, the electric motor 6 and six devices A. for separating the heddles are arranged, a device A belonging to each harness 3 or row of: heddles. The motor 6 imparts rotation to the shaft 8 through the interposition of a Worm gear and a belt drive 7, whereby a crank mechanism 9 causes the front part "10 of a carriage to reciprocate; therear part 11 of the carriage being tive connection with a control lever 29.

rum

at intervals coupled to the front part as will be fully explained hereinafter. The carriage 10, 11 is guided with its wheels on a track 12 provided on the main carriage 4 of the machine. During every to and fro movement of the front part 10 of the carriage the latter abuts with its axle pin 13 (Figs. 2 and 4:) against a lever 14 of a ratchet mechanism 15 and displaces the latter against the action of a spring, so that the worm gear 16 imparts a turning motion to the vertical shaft 1 7. A pinion 18 is fixed to the lower end of the shaft 17 and cooperates with a toothed rack 19 mounted on the frame of the machine and the intermittent turning motion of the vertical shaft 17 causes a step by step movement of the machine carriage i along the harnesses 3 arranged one behind the other according as the heddling work proceeds. Upon the return movement of the carriage 10, 11 the part 11 of the latter knocks against the end lever of a lever gear'20, which is operatively connected to a spring loaded ratchet bar 21. That lever is rocked through such an angle that the ratchet bar 21 cooperating with the pins of a head 22 of the device 5 turns the head 22 through one pitch. whereby the pattern mechanism is moved accordingly. The latter is provided with rollers 23 arranged on bare and serves to control levers 24;,

Fig. 6, and spring actuated pins 25 which are arranged in one row parallel to the movement of the carriage 10, 11. Six levers 24: are provided each of which'is connected by a link 26 to a supporting lever 27. On each supporting lever 27 a lifter 28 influenced by a suspension spring rests, the lifter forming part of one ,ofthe six devices A for separating the heddles and being in operzlkknife 80 is common to the six lifters 28 and rests with itsends in the two supporting and guiding arms 31. Pins provided in the ends of the knife'30 project beyond the arms 31 and enter slots of levers 32 Fig. 2. The knife is thus reciprocated by the rocking of the levers 32 and the latter are fixed to a shaft 33 common to both and the shaft 33 is in operative connection with a control lever 36 vby means ofa link and lever 34 and a shaft 35. The control lever 36 receives its movement from a cam disc-37 .(Figs. 1%) .fixed to the shaft 8 and is pressed against the lateral face of said cam disc by the action of a tension spring.

When the levers 24 are not influenced by one of the rollers23 of the pattern device they are in such a position that the lifters 28 restingon the supporting levers 27 and being lowered in comparison to this position shown .in Fig. 6 are out of the path of theknifeSO. If one of the levers 24; is rocked out of its neutral position by the action of a roller 23 the supporting lever 27 essons connected to said lever 24 is then so rocked that it lifts the respective lifter 28 into the path. of the knife 30. llfhereupon this lifter 28 is moved to and fro when the knife is reciprocated as the lifter is engaged by the knife to take partin the forward movement of the latter and is influenced in a. corresponding manner by its tension spring during the backward movement of the knife. Thereby the corresponding device it. for

separating the heddles is rendered opera.- tive; the details and the working of the device for separating the heddles will be enplained hereinafter.

Upon the turn ng motion of one of the lovers 2f caused by the pattern mechanism the bolt 25 corresponding to the lever lifted in its guide against the action of the spring in order to uneouple the two parts of the forwardly moving carriage 10, 11. The front part 10 of the earriage is yn'ovidcd on its lower side with a projecting beak 38 (Fig. and an inelinml facing Pill. lVhen the two parts 10 and ll. of the carriage are coupled together (l ig. T) the beak 3-8 of the front part 10 of the carriage is in engage ment with a spring loaded eoupling hook 4:2 'n'ionnted on the front extension =l-l of the rear part 11 of the carriage. while a spring loaded lever 43 mounted on the rear part of the carriage is kept .in its inoperatiw position b" :1. pin at provided on the lever and bearing against the inclined facing The lifted pin 25 is situated in the path of the coupling hook 42 which is p rovided with :1 lateral arm striking against the pin 25 when the carriagestarts to move. 'llhorehy the coupling hook 4:2 is r-iwung out of engagement with the beak 38 against the influence of the spring and the parts it) and ll :1 re uncoupled. Thereupon the rear part .ll of the, carriage remains stationary and the front part 10 of the arrizige continues its movement 'aused by the eranl; gear ti and ie turns into its initial po ition at the end of the stroke. The end face of the extension +11 of the rear part of the carriage abuts now against the bolt 25 causing the turning of the coupling hook 312. and the lever l3. which turns in the inward dir ction us the front part 10 moves away. einbrin'cs the pin and secures the rear part of the carriage in posi-- tion. l hen the part it) moves backward the inclined facing 39 causes the turning motion of the securing lever '13 in the outward diree tion and the beak 3S acts upon the coupling hook 2 and the two are cane-red to engage each other. The rear part ll is thus eoupled to the front part 10 of the carriage and both parts return together into the r init al position, whereupon both parts move forward together up to the point in vi'hich a pin 25 lifted by the pattern tltlr'lt": causes the two parts to become uncoupled.

The front part 10 of the carriage is proiii] ill)

vided with two parallel bars to one of which a vertical support 46 is attached. A bar 48 is parallel to the support 16 and the distance between bar 48 and support 16 may be adjusted by means of two bolts 47. To the bar d8 two spindles 1-9, 50 are fired one above the other, between which a threading needle 51 having a long shaft is located and is also fixed to the bar 18. Between the spindle 50 and the needle 51 a further spindle 52 is arranged and attached to the support 46. A vertical shaft 53 is mounted on the support 16 and provided at its lower end with an arm 5 1 which cooperates with two stop pins 55, 56 (Figs. 3 and 4) provided on a rail 57 fixed to the carriage d. The shaft 53 is further provided with two arms 58, which are operatively connected to thetwo bolts 47. On the other bard-5 of the front part 10 of the carriage an upright plate 59 is fixed, provided with a switch 60 which is mounted on a screw bolt 61.

To the rear part 11 of the carriage a vertical support 62is fixed to which a horizontal bar 63 is attached carrying a plate 6% (Figs. The bar 63 situated in the vertical plane passing through the threading needle 51 and provided with a slotted stirrup 65 and with a funnel 65 open at its end for receiving; the threading needle 51 and adapted to hold the heddle to its threading position. The funnel 66 is integral with the separating member 67 mount-- ed on a pin 68 provided at the end of the bar 63 and adjacent to an upright plate 69. A plate 7 0 provided. at the front end of the funnel 6G and projecting in the downward direction forms together with an extension 71 at the rear end of the funnel a bearing for the shaft 72. The latter carries a control arm 73 and a pressure arm '74; cooperating with its free end with the mouth of the funnel 66. The shaft 72 is influenced by a tension spring 75 tending to turn it in such a direction that the control arm 73 is held towardsthe plate 9 for the purpose of co operating; with an inclined facing 77 (Fig. 11) provided on the plate 69. In the front part of the funnel 66 to both sides of its mouth guide members 77 for the heddle B are arranged, the latter being held by the pressure arm 7% at the front end of the funnel whereupon the threading needle is passed through. the eyelet of the heddle.

When the carriage 10, 11 travels forward the above described members forming the threading device and carried by the two parts 10 and 11 of the carriage, which parts are then in the relative position illustrated in Fig. 1, are moved in the direction of the harnesses 3 arranged one behind the other. If, as is assumed in Fig. 5, the foremost harness 3, i. e. the foremost row of heddles has to be dealt witlnthe foren'u'ist pin 25 lified by the pattern device causes the uncoupling of the two parts of the carriage so that the rear part 11 and its accessories are brought to a standstill, the separating member 67 being then situated in the plane of the foremost row of heddles. During the further. travel of the front part 10 of the carriage the switch 60 abuts with its inclined ront part against a lever 7 8 carrying a rollcr and causes a turning of this lever about its fulcrum mounted on the vertical support 62 and against the action of a spring whereby a rod 79 connected to the member 67 is pulled in the downward direction. Thereby the member 67 together with the funnel 66 and the parts connected to the latter are turned about the pin 68 from the lower position shown in Fig. 1 into the upper position illustrated in Figs. 5 and 10 and are held in this position as long as the lever 78 rests on the horizontal portion of the switch 60. During this interval the threading needle 51 moving together with the front part 10 of the carriage, which continues travelling, is projected through the eyelet of a heddle ll which has been brought into the position in front of the funnel by the separating device A belonging to the first row of heddles. lly the turning movement of the member 67 heddles which happen to be too near to the heddle to he threaded are pushed aside and the funnel 66 is moved into the path of the advancing); threading needle 51 and acts as gu dance to the latter. During the final stage of the movement of. the funnel 66, i. e. when the control arm 7 3 slides over the inclined face 76, the pressure arm 74 is turned by the action of the tension spring 75 into its operative position (indicated in dash and dot lines in Fig. 16). -Thereby the arm 74 are s the eyelet of the heddle B, which is obliquely to the face of the mouth of the funnel 66 to bear against the latter which has been widened to faciltate the turning of the eyelet and to provide for a good seat of the latter in the funnel. whereupon the threading needle 51 is passed through the eyelet and the warp thread or an auxiliary thread to which the warp thread has to be lniottcd later on in the loom is inserted into the hook of the needle. lVhen the switch (30 advancing: further with the front part 10 of the carriage releases the lever 7 8. the latter is turned by the action of the spring so that it pushes the connecting rod 79 in the upwarddirection whereby the member 67 and the funnel 66 together with the parts connected to the latter are turned inthe down- 'ard direction, i. e. arercturned into their initial positions. Simultaneously the pressure arm 74: returns into its inoi ierative position and releases the heddle which has been tln'eaded.

The spindles 19, 50 and 52 are advanced z-iiin'uiltaneously with the threading needle 51 in accordance with the movement of the ill) front part 10 of the carriage. The hcddle B through which the'threading needle 51 has passed, is situated on the right hand side of the spindles 9, 50 and 52 in Figs. 3 and 12 and to the left in Fig. 2. The spindle 5:2 serves to keep other heddles situated on the respective separating device away from the hedd'le to be threaded and the spindles 4.9 and 50 act as lateral upper and lower supports to the heddle on being threaded. When the front part of the carriage. approaches the end of its movement the arm 5% on the vertical shaft 53 impacts against the stop pin 56 provided on the rail 57. Thereby the shaft 53 is turned through a determined angle and the arms 58 cooperating with the bolts 4.7 move the bar 48 together with the threading needle 51 and the two spindles 49 and 50 towards the support 46 by a corresponding amount. Tn consequence thereof the he ddle which has been threaded is moved in the harness towards the left, when looking; at Fig. 2 up to the other previously threaded heddles of this harness.

- switch. The plate serves for effecting a lateral displacen'ient of the heddles if a heddle of the hind rows has to be threaded.

The spindles d9, 50 and 52 are returned into their initial positions simultaneously with the threading needle 51. Upon its return movement the front part 10 of the carriage abuts against the rear part 11 and the two partsare automatically coupled together and return togetherinto the initial position; in this manner all the parts carried by the rear part of the carriage return into their initial position in order to be brought forward to operate with the row of heddles selected by the pattern mechanism whenthe carriage l0, 11 starts its next for- The stroke of the thread in; needle 51 is sutiiciently large to thread heddles of any harness.

Shortly before the carriage 10, 1]. reaches its initial position the arm 54 of the vertical shaft 53 strikes the stop 55 on the bar 57. Thereby the shaft 53 is turned back into its initial position so that the bar 48 is moved. in the lateral directionand. togetherwith the threading needle 51 and the spindles l9 and 50 takes up its initial position.

To an upwardly extending support on the main carriage 4 a horizontal bar 81 is eas es which a bell crank lever 82 is The latter acts as the device for removing the threads trom the hook of the threading needle and is held in. the position illustrated in Fig. 1 by the aid of a stop pin 83 1",) provided on the support all; when the carriage 1t), 11 is in its initial po sition. lVhcn the latter moves tor-ward the hell-crank lever 82 is swung: into the position illustrated in Fig. 5 by the action Hill a spring 8 1-. Upon the return mowuucnt of the carriage l0. 11 the bell-crank lever 82 caused to turn into its first mentioned position by the stop pin 83 whereby av hook 85 provided at the end of the longer arm of the lever 82 catches the warp thread inserted in the hook of the threaded needle 51 and lifts itout of said hook, so that the needle 51 tree for pulling another warp thread through the eyelet oi? a hcddle.

Corscquently the contact plate 95 closes an auxiliary circuit in the conductor 91 through the two contact levers 93. 94, in which circuit an clcctromogrnct Eli; is arranged. the armature of which is now attracted. Thereby a loclciup; member 97. forming); part of a switch and having been up to then secured in position by the arnurture, is released. so that the switch can be turned by the action of a tension spring and interrupts the motor circuit 92, whereupon the machine stops and can be inspected. ll hen the machine works normally and heddles are presented for threading in the tlbOVO-(lQSCFllJGtl manner. the connection of the conductor 91 over the contact Ill pieces 93, 94 is interrupted when the contact plate 95 connects the contact arms 93. 94 with each other. i

The six devices A for separating the heddles of the six harnesses are mounted in a holder 99 carried by the frame work of the carriage 1. To this end a vertical support 100 is provldcal with each devlce A, on which support the control lever 29 is mounted and the tension. spring 28 cooperating with the lifter is fixed. At its upper end the support 100 carries a head'101 above which a flat bar 102 F iigs. -28) is supported. On the upper side of the latter two locking lovers 103 and 104: are mounted which are interconnected by a tension spring 105 and are ordinarily held in their position of rest by said spring. Furthermore a spring 107 isfixed to the bar 102 by means of a set screw 106. On the upper side of the head 101 a slotted lever 109 (Fig. is pivoted abou set screw 108 and is held in its position of rest by a spring 110; in this po'ition an extension 111 on the lever projecting into a slot of the head 101 abuts against the latter. The slotted lever 109 is provided with an upper guide plate 112 and with a roller 118. With the latter a slide 11 1cooperates which is guided in a longitudinal slot 115 of the head 101 and is operatively connected to the control lever 29 by means of a pin 116 entering a slot of the lever. A pin 118 projects into a slot 117 of the slide 11 1. the pin 118 being provided on a sliding piece 119 guided in the slot of the lever 109. Upon the sliding piece 119 a spring loaded lever 120 is mounted which is provided with a beak 121 at its lower side cooperating with the slotted. lever 109 and with a switch The switch 122 is mounted in the head 101by means of a. pin 123 and is ordinarily held in its position of rest by mean of a spring 12 1 (Fig. 25), in which position a pin of the switch abuts against the head 101. .On the lever 120 the part 126 adapted to supply the heddles is mounted on which a tension syni'ing 120' connected to the lever 120 acts in one direction and a tension spring 127 connected to the lever 127 acts in the other direction. The lever 12'. is mounted on the lever 120 by i'neans of a pin 128 which also serves as fulcrum to the part 126 and it is provided with a stop pin 129 for the part 126. Two spring loaded levers 130. 131 are further mounted on the sliding piece 119. The lever 130 action: as fcelcr is provided with a. shorterarni arr: ged below its longer arm and the shorter a ll! cooperates with a lever 131 acting as gripping device for the heddles the lever 131 being provided with anotch 132 and a stop pin 133.

The "e'parating device for the heddles works as follows: v i

Let is be assumed that thellfter 28 follows by the influence of its tension spring the receding knife (Fig. 0) during the whole movement of the latter, the sliding piece 119 performs then its full stroke through the cooperation of the slide 114. The sliding piece moves thereby from left to right along the slotted lever 109 when looking at the Figs. 20 and 23-28. The beak 121 of the lever 120, which at the beginning rests against the front of the slotted lever 109, pushes during this displacement (forward movement) the sliding piece 119 up the inclined face 122 of the switch 122, which face projects into the path of the sliding piece 119 and is deviated by the switch to the rear of the latter. Thereby the lever 120 is turned such that the gripper 126 getsbehind the plane of the row of heddles of the respective harness (this position of the lever 120 is shown in F 27). As soon as the beak 121 of the lever 120 leaves the rear side of the switch 122, owing to a corresponding' forward movement of the sliding piece 119, so that the switch does no longer act as an abutment, the lever 120 is turned by the action of the tension spring into its position of rest (F 24) which is determined by a stop pin. Thereby the feeder 120 enters the row of heddles in front of it and separates therefrom a number of heddles B, for in stance four heddles 23).

The four heddles B, which have been separated by the feeder from the row of heddles are now moved towards the left with regard to Fig. 23, when the sliding piece 119 performs its return movement. which is transmitted by the lifter 28 during the forward movement of the knife 30. Upon the return movement of the sliding piece 119 the beak 121 of the lever 120 turns the switch 122 againstthc action of thespring 124: in order to be able to pass that part of the switch which projects into the path of the beak 121, the latter abutting then against the front of the slotted lever 109. Thereupon the roller 113 of the slotted lever 109 is reached by he inclined facing 11 1 of the returning slide 114 and the slotted lever 109 is turned about its fulcrum pin 108 against the action of the spring 110 (this position of the slotted lever 109 being shown in Fig. 26). The feeder 126 moves the four heddles, separated from the other heddles during the return movement of the sliding piece 119 beyond the locking lever 103, which has been turned correspondingly, into the space present between the flahiron shaped end part of the spring 107 and the lever 103. Duringthe subsequent forward movementof thesliding piece 119 the slotted lever 109 swings back into its position of rest and the feeler lever 130, arranged on the slotted lever 109 and projecting into the notch 132 of the grippinglever 131, as is shown in Fig. 2 1, contacts with the foremost of the four heddles previously conveyed by the feeder 126 to the space between the spring; 107 and the. locking lever 103. Thereby the ieeler lever 130 is turned against the action of its spring and recedes from the notch 132 of the gripping lever 131, which in its turn is so turned by its spring that it enters with its prong between the foremost and the following heddle of the supply of the heddles present on the sep-- arating device (Fig. 27). The foremost heddle is now caught between the prone ot the lever 131 and the feeler lever 130 and in a slot 119 of the sliding piece 119 respectively. This separated single heddle B is moved by the return movement of the sliding piece 119 into the space 1334 (Figs. 23 and 28)-between the end of the spring 107 and the locking lever 10%. in this position the heddle B is presented to the advancing threading device particularly to the guide members'T T in order to be held in position at the funnel after the heddle has been released by the gripping'lever 131 of the separating device. This is eii'ected in that during; the continued backward movement of the sliding piece 119 the gripping lever 131 abuts by means of its stop pin 133 against the edge 112 of the plate 112 provided on the head 101, thereby the lever 131 is turned to such an extent that its prong is withdrawn from theslot 119 of the slidingpiece 119, so that the heddle B does no longer take part in the further displacement movement of the sliding piece 119; during said turning movement of the gripping lever 131, the feelerlever 130 comes again in engagement with the notch 132 so that it is again in the position to start action. During the continned backward movement of the sliding piece 119 the slide- 11 1 with its inclined face 114: reaches the roller 113 ofthe slotted lever 109 so that the latter is turned us has been explained above. Thereby the sliding piece 119 is moved in an oblique rearward direction out ofthe plane of the row of heddles, so that the path of movement of the heddle passed through by the threading needie 51 and moved laterally by the spindles 49 and 50 is now unrestricted. During the subsequent forward movement of the sliding piece 119 the gripping lever 131 grips in the manner described above another heddle from the supply of heddles on the separatinn; device between the locking lever 103 and the spring-107. Owing to the abutting 0" the feeler lever 130 and of the sliding piece 119 respectively against the separated supplyo i heddles the forwardly moving sliding piece is held up so that the beak 121 of the lever 12 0 is at first not allowed to move beyond the rear side of the switch 122 and travels therefore the same path as on its forward movement when the sliding piece 119 returns a that the feeder 126 does not eashes reach the heddles to be separated and to be supplied to the separating; device; the lifter 28 does not follow the whole return movement of the knife 30. However before the supply oi? heddles on the separating device is exhausted, the sliding; piece 119 attains its full stroke so that the beak 121 oi the lever 12.0 move v beyond the switch. The above described working is then repeated whereby the feeder supplies heddles from the row o'l heddlee to the separating device, so that a fresh heddle may always be presented to the threading device.
